boxing

When a value type is boxed, it is placed inside an untyped reference object. So what causes the invalid cast exception here?

long l = 1;
object obj = (object)l;
double d = (double)obj;

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
